A Spruce Tree 



The spruce is one of the most familiar and most highly 

 prized of evergreens in many of our northern forests. Its res- 

 inous exudate was formerly very popular as a commercial product 

 known as "spruce gum." Nowadays the demand for chew- 

 ing gum has so increased that it has been necessary 

 to find other materials for its manufacture, 

 and the once-familiar spruce gum 

 has practically disappeared 

 from the market.
